Claims.

My invention relates to remote radio control, the primary object of which is to provide means wherein the radio set may be operated remote from the units and members of the same. With 5 my remote control, a radio set may be operated conveniently from a distant point and while the operator is leisurely seated away from the radio set.

A' feature of my invention resides in means adapted to operate the condensers and tubes of a radio tuning set remote from the same. I provide a suitable handle member which may be engaged and operated to tune the radio set from a distant point. This permits the radio set to iii be placed in any convenient place in the home and by means of a flexible connector, together with an operating handle means, the radio receiver may be tuned as desired.

It is a feature of the invention to provide means in the form of a handle or holder which may be readily engaged and held in a convenient manner so that the operating members associated with the handle can be operated in a manner to tune or adjust a radio receiver or the radio apparatus of a similar nature.

These features, together with other details and objects of my invention will be more clearly and fully set forth hereinafter in the specification and claims.

In the drawings forming part of this specification:

Figure 1 illustrates diagrammatically one form of my radio control.

Figure 2 illustrates another form of the same.

Figure 3 illustrates a different form of the handle control.

Figure 4 is a perspective view of the handle control illustrated in Figure 3.

Figure 5 is a section on the line 5-5 of Figure 3.

Figure 6 is a perspective detail of a portion of a radio tuning set.

Figure 7 is a detail of a side illustration of a portion of a radio tuning set.

My radio control A is adapted for the purpose of operating the radio tuning set B, only a portion of which is illustrated in the drawings, from a point remote from the set B, so that the operator may sit in any convenient position or place and operate the radio set. The remote control A consists of a handle piece 10 which may be held readily in one hand and is provided with an operating button 11 which is connected to the flexible shaft 12 which extends to the operating gear 13, which in turn engages the gear 14 on the shaft 15 of the condenser 16. When the button 11 is operated the flexible shaft 12 will rotate the gears 13 and 14 and turn the operating shaft 15. This will adjust the condenser 16in a manner to tune the radio set B.

In the handle member 10, illustrated in Fig ure 1, I provide also an operating button 18 which is adjacent the operating button 11 and which is connected to the flexible shaft 19. This flexible shaft 19. extends to the operating shaft 20 in a manner to control the volume through the resistance 21 which is provided with the operating arm 22 operated by the shaft 20 and operates in the ordinary well known manner.

Thus by means of the control A with the han- 7 dle 10, and by operating the buttons 11 and 18, the radio set B can be set to tune into any desired station. The flexible shafts 12 and 19 may be of any suitable length, thus the operator may operate the radio set remote therefrom in the same manner as if the operator were adjacent the radio set.

The control A may be in the form illustrated in Figure 2, and in this construction the handle 24 is of a tubular nature, while the operating button 25 is adapted to operate the flexible shaft 26, which in turn operates the gears 13 and 14 to operate the condenser 16 mounted on the shaft 15.

The control handle A is provided with an operating button 27 which operates axially with the button 25 and is connected to the operating rod 28 in a manner so that when the button 2'? is pulled outward, the rod 28 is operated to operate the arm 29 of the resistance 30. In this construction the button 2'7 operates the volume control.

I have also illustrated another form of operating handle for my control A, such as 32 which is provided with a stock portion 33 which can be engaged by one hand, and pairs of operating buttons 34 and 35 are positioned on either side of the handle 32, so that they may be operated either with the right or left hand.

The operating buttons 34 are mounted on the shaft 36 and are adapted to operate the pinion 37 which engages with a rack formed on the rod 38 extending longitudinally in the handle 32. This rod 38 is connected to the small rod 39 and the rod 39 operates to operate the lever. arm 40 of the resistance 41 of the radio set B, illustrated in Figure 7.

The buttons 35 of the handle 32 are mounted on the shaft 43 and by means of a worm gear 44 mounted on the shaft 43, the gear 45 is operated to rotate the same which is connected through the sleeve 46 to the flexible shaft 4'7.- The flex- 110 ible shaft or is connected to the gear 13 which operates the gear is oi the condenser is cit-the shaft 15. 4

The handle 32 is provided with a galvanometer C which is mounted in a convenient position on the same and which is connected by the wires d9 with the potentiometer D, so that when the chart 15 is Operated the galvanometer will register the reading of the stations and the operator can readily apprehend the setting of the galvanometer to tune in stations according to the reading of the galvanometer. The galvanometer may be placed, as illustrated in Figure 8, in the instrument board of the tuning-set 13.

Thus the operator by means of my remote control A may operate the radio set B from a distant point in a manner to readily adjust the parts of the radio set to tune in any particular jstations.

This provides a means or controlling the tuning of a radio set in a more convenient manner than has 1 been done heretofore, as it permits the operator to be seated leisurely at any convenient place in the home and by means of the flexible connector and control A, tune in the desired radio station. Then when the station has been tuned in the control A may be laid aside until it is again wanted.

I believe my remote control for radio sets provides a means of operating a radio set in a more convenient manner than has been done heretofore and in many instances it will permit the radio set to be placed man out of the way position or even in another room, and yet giving the operator an ,opportunity to tune in any desired station with virtually the same accuracy as is accomplished where the operator must be near the radio set so as to be able to operate the same. My control may be easily detached and disconnected so that when it is not desired for use it may be laid aside or readily attached when it is again wanted for the purpose of operating the radio m. In accordance with the patent statutes I have described the principles or operation of my radio control, and while I have illustrated a particular -formation and arrangement of the parts. I desire to have it understood that these are only suggestive of a means or carrying out my invention and thatthesamemaybeappliedtousesotherthan those above set forth and carried out by other forms of construction, within the scope of the following claims without departing from the spirit of. my invention.

I claim:
